Third world countries aren't exactly known for their competence, but they are known for their corruption. Unfortunately their incompetence sometimes also gets in the way of their corruption; if they figured out to manage things responsibly, they could embezzle even more money.
Here would be an even better plan. Hand over control of all of this to Norway to set up a sovereign wealth fund. Make the terms that Norway collects 20% of all withdrawals. Sit back and grow rich as the responsible Norwegians run things and make good decisions and also grow more rich themselves.
this seems like a massive massive mistake tbh, if they really do have that much they should be doing it themselves.
